A sledge (including load) has a total mass of 141 kg. It is pulled on level snow by a dog team exerting a horizontal force on it. The coefficient of kinetic friction between sledge and snow is / = 0.074. How much work is done by the dog team pulling the sledge over a distance of 2,372 m at constant speed? Take g = 9.8 m/s2. Please round your answer to the nearest whole number (integer).A motorcyclist is trying to leap across the canyon by driving horizontally off a cliff at vo = 13 m/s. ho = 27 m and h; = 10 m. Ignoring air resistance, what is the speed, v (in m/s), with which the cycle strikes the ground on the other side as shown? Take g = 9.80 m/s2. Please round your answer to one decimal place. VO ho
